Abstract

The body is oval, and the legs terminate in large, dark claws well adapted to cling to hairs. Hog lice are bluish-gray in color. They are found only on hG>gs except in very unusual cases.

Lice suck blood from the host, and may occur on any part of the body. They prefer the lower half of the sides, the neck, shoulders, and flanks . Young lice may congregate in the ears during cold weather. Dipping or spraying in the fall are the recommended control measures. Several insecticides can be used, the following are suggested:
